Hydroc Prime


Concrete waterproofer, hardener and corrosion inhibitor

Order Request


Hydroc Prime is a highly active penetrating waterproofer, corrosion inhibitor and durability enhancer for concrete utilising the existing Aardcure Catalyst technology. This chloride and silicate free solution deeply penetrates new or old concrete, increases surface abrasion resistance, reduces moisture vapour transmission and permeability of concrete from water and chemical attack. Hydroc Prime is used as a primer for Hydroc waterproofing and repair mortars.

Application Instructions

Surface Preparation

Surfaces must be clean, dry and free of ponded water prior to application.

Clean surface to remove any dirt, laitance, previous coatings or curing agents that may prevent penetration of the material. Ensure all residual cleaning agents or strippers are removed and surface is flushed with clean water and allowed to dry thoroughly. Minimum preparation of pressure washing at a minimum of 2000psi is recommended.

Confirm absorbency of surface with a light water spray, ensuring penetration into the surface is achieved.

Application Method

Using a low-pressure sprayer fitted with an adjustable spray tip, apply a single even coat to the surface at a sufficient rate ensuring to achieve nominated application rate. For excessively degraded substrates reapply to areas of greater porosity after 2 to 4 hours with additional Hydroc Prime.

Let treated surfaces dry thoroughly, approximately 30 to 60 minutes before applying any further coatings such as curing agents.

For application on freshly placed concrete, apply after final trowel finishing once bleed water has gone and application procedure will not mar the surface. Joints can be cut prior to application of the Hydroc Prime but dust and debris from saw cutting must be removed. It is recommended to cure the concrete to industry standards after the Hydroc Prime is applied.
